Outrage over the outage

Ashley Chaifetz, a PhD student studying public policy at UNC-Chapel Hill, writes:

Winter storm Pax pelted North Carolina with an initial dose of snow and freezing rain, and is now traveling north on I-95. Although I’ve been fortunate so far, power outages are already affecting hundreds of thousands of Southerners. Losing electricity can be a nightmare — especially if it is for more than a couple of hours.1920543_10152192564303431_259801825_n
 
Alongside 4,500 of our neighbors, we spent four nights in a row without power in DC in the summer of 2013. It was  hot and humid, with temperatures in the 90s F not C). Our attempts to cook without electricity in the dark felt very much like a modern version of Little House on the Prairie. All I could think was that, if this was hurricane or a snowstorm, we would have had time to prepare (but maybe not).
 
There are currently 800,000 people without power from the snowstorm, leaving many with a food safety situation — a refrigerator with most of last week’s vegetables, defrosting chicken, jars of jams, peanut butter, and tomato sauce, cartons of eggs, chunks of cheese, quarts of milk, and once-canned goods stored in Tupperware. I know I would not be ready to toss all those vegetables into the compost, but depending on the time and temperature, some fridge contents will have to go.
 
According to USDA FSIS’s estimates, a closed fridge will keep its contents at refrigeration temperatures for about four hours and a closed freezer will keep food close to freezing for about 48 hours after the power goes out. If food temperatures rise above 41°F for more than four hours, pathogens within any meat, seafood, poultry, and dairy products (as well as many cooked foods) can grow to problematic levels. There is an increased risk in pastatemperature-abused leftovers made with high-protein foods (meat and meat substitutes); soft cheeses; milk and cream-based products; sliced tomatoes and cut leafy greens; and cooked pasta or rice. In the freezer, if meat, poultry, seafood or dairy products still have ice crystals, you can refreeze them when the power returns. If they are thawed for more than a couple of hours, they can be risky.
 
Making the risk management decision without a fridge/freezer thermometer and a food thermometer is tough and losing a bunch of food can be an expensive lesson. It isn’t a fantastic idea to guess temperatures without a thermometer, either; a guesstimate can increase risk of illness or lead to more waste.

About Ben Chapman

Dr. Ben Chapman is an associate professor and food safety extension specialist at North Carolina State University. As a teenager, a Saturday afternoon viewing of the classic cable movie, Outbreak, sparked his interest in pathogens and public health. With the goal of less foodborne illness, his group designs, implements, and evaluates food safety strategies, messages, and media from farm-to-fork. Through reality-based research, Chapman investigates behaviors and creates interventions aimed at amateur and professional food handlers, managers, and organizational decision-makers; the gate keepers of safe food. Ben co-hosts a biweekly podcast called Food Safety Talk and tries to further engage folks online through Instagram, Twitter, Facebook, YouTube and, maybe not surprisingly, Pinterest.

    The author likened the power outage to a situation such as you might find on “Little House on the Prairie”. Having lived in such a situation as that, you learned to live with what you had, and survived. you did not curse the darkness, for if you did you found it was futile and rewarded you with nothing. but lost time, which in such situations can be and often is calamitous. The era of push button exemption and escape is not here and probably never will be if you consider the salvaged lives and equipment of space exploration. Not a good idea to stand your ground and complain. Learn your surroundings and be constantly aware of what must be provided by YOU, in order for your own survival.

    Don’t forget all that snow is ~32 degrees! pack bowls full of snow and put into the fridge to keep things cold (use a thermometer to check!). Should add hours before it gets warm in there. My mother called it the ice box for a reason.
